Overheating and temp gauge all over the placeI have a 2005 Chevy Cavalier it has been overheating. My temp. gauge has gone haywire. My cooling fan has not been coming on. My upper radiator hose gets hot. The lower hose stays cold...

SES Code IAT Temp Sensor and TRAC OFF After ReplacedIgnition control module on top of valve cover,plugs and wires. Think fuel pumps now going. It has never been replaced to my knowledge. Replaced air temp sensor in the air intake tube{right after the air filter.

Battery Going DeadReplaced the alternator but still does not charge. Tested wires to the PCM. How can i be sure the computer is bad on my car.

2000 Cavalier StallsWhen coming to a stop and turning and pressing the brake pedal, the car dies out. Has to add fuel. Need to keep foot on gas to keep it running, then stalls out again. Check engine light is also on.

What IS This Part Called?My son put his 2000 Cavalier in the ditch last night. He was going very slow, but there is a frozen ridge in the ditch. It was very foggy and our gravel road is mush right now that sucked him right off the road when he got too close to the edge. We found this part when we pulled the car out.
